Hansel & Gretel follows the brother-sister team, Hansel and Gemma Arterton's Gretel, who were traumatised by their run-in with a crone as children. Instead of retreating from the world, they roam, taking down cackling witches wherever they threaten local villages.

Armed with sophisticated (for medieval / fairytale times, at least) weaponry, the pair have become a well-oiled witch-slaughtering service. But their latest mission isn’t going quite to the usual schedule. Instead, the dangerous creatures appear to be hunting them – and things get worse when they kidnap Gretel.

This trailer might not quite be enough to convince everyone, but it does nudge the entertainment-o-meter needle a little further into the green. We’ve also heard some positive buzz on this one, so we’ll wait and see when the full film arrives on March 15.
